finest and rhel/centos 7.1

[Charles Weber]

Hi everyone,
I am building a large storage server and noticed to my delight that mkfs.xfs in 7.1 now supports finobts=1. But I get mount errors saying below. Since the FS in question mount fine so long as I don’t specify finobts=1 while formatting, should I assume the rest of 7.1 is not yet ready for it? Or is there some option I missed?

thanks,
Chuck
